We have been given a right angled triangle, hypotenuse is known, and angle has been given. we need to find the adjacent side to the angle.

we use trigonometry ratios.
the ratio where we relate the hypotenuse and adjacent side is the cosine.
cos θ = adjacent side / hypotenuse 
where θ = 39°
hypotenuse - 17 m
adjacent side - x
we need to solve for x

cos 39° = x / 17
cos 39° = 0.77
0.7771 = x/17
x = 0.7771 x 17
x = 13.21 m
distance from Roman's feet to the base of the pole is 13.21

3. The yearly profits of a company is $5,000. The profits have been decreasing by 6% per year.
natka813 [3]

Answer:

5000 X (0.96)^n

$3607

Step-by-step explanation:

Profit decreases at a rate of 6% per year = 100 - 6 = 96%

In year 1, profit would be = 5000 x 0.96 = 4800

In year 2 = 5000 x 0.96^2 =

5000 X (0.96)^n

5000 X (0.96)^8 = $3607

A regular number cube is rolled. What is the probability that an odd number will not be rolled?
mixer [17]

Answer:

1/2

Step-by-step explanation:

A regular die has 3 odd numbers (1, 3, and 5) and 3 even numbers (2, 4, and 6). The question asks for the probability that an odd number will not be rolled. This is the same as asking the probability of an even number being rolled. Since we have 6 numbers in our data set and 3 are even, we can deduce that 1/2 of them are even and the probability of an even number being rolled is 1/2.

Digiron [165]

Answer:

\sin \: x -  \cos  x \:  + c

Step-by-step explanation:

\int \frac{cos2x}{ \sqrt{1 - sin2x} } dx \\  \\  =  \int \frac{ {cos}^{2}x -  {sin}^{2}x }  { \sqrt{ {sin}^{2}x +  {cos}^{2}x - 2sinx \: cosx  }  } dx \\  \\ =  \int \frac{ ({cos}x -  {sin}x )({cos}x  +   {sin}x )}  { \sqrt{  {({cos}x -  {sin}x )}^{2}  }  } dx \\  \\ =  \int \frac{ ({cos}x -  {sin}x )({cos}x  +   {sin}x )}  {{  {({cos}x -  {sin}x )} }  } dx \\  \\  =  \int({cos}x  +   {sin}x)dx \\  \\  = \int{cos}x  \: dx +    \int{sin}x \: dx \\  \\  =  \sin \: x -  \cos  x \:  + c
